#3/8# of the marbles in the bag are blue.

Explanation:

A ratio of #5# to #3# means that for every #5# red marbles, there are #3# blue marbles. We also need a total number of marbles, so we must find the sum of red and blue marbles.

#5 + 3 = 8#

So #3# of every #8# marbles in the bag are blue. This means that #3/8# of the marbles in the bag are blue.
